N5172B/82B with Option 431
[:SOURce]:RADio:DMODulation:ARB:FILTer:BBT <val>
[:SOURce]:RADio:DMODulation:ARB:FILTer:BBT?
This command changes the bandwidth–multiplied–by–bit–time (BbT) filter parameter.
The filter BbT value can be set to the minimum level (0.1), the maximum level (1), or in between by
using fractional numeric values (0.100 to 0.999).

Key Entry
Filter BbT
Remarks
This command is effective only after choosing a Gaussian filter. It does not have
an effect on other types of filters.
To change the current filter type, refer to
“:FILTer” on page 248

:FILTer:CHANnel
Supported
N5172B/82B with Option 431
[:SOURce]:RADio:DMODulation:ARB:FILTer:CHANnel EVM|ACP
[:SOURce]:RADio:DMODulation:ARB:FILTer:CHANnel?
This command optimizes the Nyquist and Root Nyquist filters to minimize error vector magnitude
(EVM) or to minimize adjacent channel power (ACP).
EVM
This choice provides the most ideal passband.
ACP
This choice improves stopband rejection.
*RST
EVM
Key Entry
Optimize FIR For EVM ACP
